Abstract

L'invention porte sur des structures de moteurs c.c. ou c.a. (universels) dont les branches du rotor sont munies de bobines à enroulement concentré. Le nombre de segments du collecteur est supérieur à celui des branches du rotor. Plusieurs bobines sont enroulées sur une même branche. Les extrémités des bobines sont reliées à différents segments du collecteur. Les cheminements parallèles des enroulements de l'armature sont parfaitement équilibrés. On obtient une distribution égale du courant dans les circuits parallèles de l'armature et aucun courant ne circule entre ces circuits parallèles. Les problèmes liés à la commutation sont faibles car la valeur des bobines d'inductance est faible. Le volume de cuivre des enroulements terminaux, les pertes par effet joule, et la longueur axiale de l'armature du moteur sont plus basses qu'un recouvrement ou une ondulation des bobines couplées. Deux types de structures sont présentés: certains où les branches du rotor sont de dimensions identiques, et certains où les branches du rotor sont de dimensions différentes.
